Set up an equation and solve, or find a common sequence.
We can set up an equation like so, using x = 1 as a base:
x(number) + (another number) = y
translate to:
1(x) + (number) = 5
The common difference is 2 for each y value, so let's use that as a multiplier:
1(2) + number = y
2 + x = 5
x = 3
So lets move up a step:
x = 2 and y = 7
We use 2 as our multiplier and 3 as our adder:
2(x) + 3 = y
2(2) + 3 = 7
4 + 3 = 7
Lets try one more case :
x = 4 and y = 11
2(4) + 3 = 11
8 + 3 = 11
11 = 11
Answer:
Step-by-step explanation:
n^2-7n is n(n-7). So n(n-7) = 0. We know n can be zero because 0* anything is 0. It could also be 7 because we are looking to multiply by 0. So to get a zero in the parentheses. you would do 0+7. Which is obviously, 7
Answer:
Slope = -3/7
Step-by-step explanation:
The formula for slope is y2-y1/x2-x1.
Substitute for the points.
5-2/3-10 = -3/7
Answer:
current value = 21000(1 - 0.05)^n
Step-by-step explanation:
This is a standard depreciation formula where n is the number of years.
Answer: (x=+17)
Step-by-step explanation:
x+35=3x+1
We move all terms to the left:
x+35-(3x+1)=0
We get rid of parentheses
x-3x-1+35=0
We add all the numbers together, and all the variables
-2x+34=0
We move all terms containing x to the left, all other terms to the right
-2x=-34
x=-34/-2
x=+17
